- To all whom/it may concern:

Be it known thatage, EDNA MOARTHUR and l ALOIs L. ROSMAN, citizens ofthe United `States, andresidents of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements'm Type-Writin Machines; and

we do hereby declare that t e f ollowin is a full, clear, and exactdescription thereo Our, invention consists in certain peculiarities ofconstruction and combination of parts hereinafter particularly set forthwith refer- 4ence to the accom anyin drawings and subsequently claimethe o ject of-said invention being to facilitate line-spacing andcarriaUe-shift in type-writing machines.

'abuts the hub of said hand-lever.

.Figure -1 of the drawings represents a side elevation of a type-writerline-spacing and carriage-shift mechanism in accordance with ourinvention, and Fig. 2 a perspective view of same.

Referring by letter to the drawings, A indicates the carriage of atype-writin machine as ordinarilyconstructed, and the platen mounted onthe carriage. The ratchetwheel C of the platen is shown engaged by itsline-spacing pawl D, hung in connection with the hand-lever E, fulcrumedon the carriage, and attached to the pawl to swing therewith we showanother lever F, one end of which The other end of the lever' F isconnected to what is hereinltermed a pull-cord G; but this devicemay bea chain or cable. The pull-cord is trained on sheaves H I andconnectedat its other end to a treadle J or an equivalent dei vicearranged and connected with reference to movement b -the operatorwithout removal of either and from writing position. Theillpplementary.- lever F being on the same crum as the awl-D and stoppedat one end lagainst the ub of the hand-lever, pull on said'su 4lement'ary lever will result infa tilt of sai 'and-lever and pawl.v Thehand-lever being actuated to tilt the pawl, the 'supplementary levermoves with said hand-lever. l A

he sheave H opposes draw of the ullcordandis shownmounted on an armattached to the carriage A, thel vsheave I being v shown mounted on anarm L in swing connection with a bracket M, attached to a post of themachine-frame. (Illustrated by dotted lines.) A thumb-screw N engagesone end of thearm L and the machine-frame to hold said arm rigid inposition to aline the sheave. I with the sheave H; but b loosening thescrew the aforesaidarm maylbe swung parallel to the adjacent endcf saidframe to economize space when not in use.

The carriage is herein shown at full limit of travel 'to the left of themachine operator, and the lever Fbein actuated said carriage is swunback to full imit of travel in the opposite irection simultaneous with alinespacing operation ofthe platen, any suitable means being employed tocoact with the lever mechanism and free thel aforesaid carriagereliminary to its shift to starting position, om which it hasstep-by-ste movement incidental to depression of t e keys and space baror bars, as is common in machines of the kind to which our improvementsrelate. n

Having thus described our invention, what lwe claim as new, and desireto secure by Letters Patent, is-

The combination in a type-Writin .machine ofthe platen-ratchet awl andits andlever, a supplementary ever having the .same fulcrum as said pawland operative in one direction to tilt the same and its hand-lever, thecarriage provided with an arm extension, an arm in connection with aframe-post, sheaves mounted in connection with said arms, a treadle, anda flexibley pull device that is trained on the sheaves and connected atits ends to the supplementary lever and treadle.

In testimony that we claim the foregoing we have hereunto set our hands,at Milwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
